Tata Motors has transformed into one of India’s most exciting automotive brands, with BS6 models like the Nexon, Harrier, Safari, Punch, and Tiago leading the segment. Tata BS6 vehicles use Bosch ECU platforms — including the advanced MD1CS018 on diesel models — that require CANFD-capable scanners for complete diagnostic access.

- Bosch MD1CS018 — Tata Nexon diesel BS6, Harrier BS6, Safari BS6
- Bosch ME17.9 — Tata Nexon petrol BS6, Tiago BS6, Tigor BS6
- Bosch EDC17C19 — older Tata diesel models (BS4)
